what is going on?!?

I started my period this afternoon sometime, but it was very light compared to the heavy starts my periods usually have. Then a few hours later, it stopped, started again, and as of right now has stopped again😂 It’s remained pretty light, a little bit of brown and some red but hardly anything. As of today when it started I was a day late but its hard to tell if this is my period or not, can someone maybe give me ideas on what this could be?
